Kendo

Helpers simplifying usage of Kendo UI components.

Table

use Riesenia\Utility\Kendo\Table;

$table = Table::create('myTableId');

// datasource can be accessed directly
$table->dataSource->addTransport('read', ['dataType' => 'json', 'url' => 'URL']);

// ... but addTransport can also be called directly on the table object
$table->addTransport('update', ['dataType' => 'json', 'url' => 'URL']);

// columns can have various types and additional options can be set
$table->addColumn('name', 'Product name')
    ->addColumn('price', 'Product price', 'price', ['class' => 'green'])
    ->addColumn('active', 'Is active?', 'checkbox')
    ->addColumn('stock', 'Stock', 'number');

// checkboxes for batch operations can be added
$table->addCheckboxes();

// class for table row can be added using 'addRowClass' method
$table->addRowClass('#: active ? "active" : "not-active" #');

// additional model options can be set using 'model' key
$table->addColumn('name', 'Product name', null, ['model' => ['editable' => false]]);

// you can use any custom column rendering class
// as long as it extends Riesenia\Utility\Kendo\Table\Column\Base
$table->addColumn('custom_field', 'Title', '\\Custom\\Rendering\\Class');

// link is built-in option
$table->addColumn('...', '...', '...', ['link' => 'URL']);

// any link attributes can be set
$table->addColumn('...', '...', '...', ['link' => ['href' => 'URL', 'title' => 'TITLE']]);

// the whole template can be overridden
$table->addColumn('...', '...', '...', ['template' => '# if (field) { # yes # } else { # no # } #']);

// it is possible to hide columns under certain table width
$table->addColumn('...', '...', '...', ['display' => 700]);

// actions are usually icons with links
// icons are bootstrap classes without glyphicon prefix
$table->addAction(null, [
    'icon' => 'music',
    'link' => 'URL',
    'title' => 'Play!'

// or predifined edit or delete operation
$table->addAction('delete');

// you can use any custom column action class
// as long as it extends Riesenia\Utility\Kendo\Table\Action\Base
$table->addAction('\\Custom\\Action\\Class');

// generally used classes can be aliased, so previous example is equivalent to
Table::alias('alias_name', '\\Custom\\Action\\Class');
$table->addAction('alias_name');

// condition is built-in option
$table->addAction('...', ['condition' => 'count > 0']);

// set text for no results (will be added as first colspaned row)

Traits

Various traits providing useful methods.

ParseDecimalTrait

Adds a protected _parseDecimal() method that transforms input to float replacing spaces, commas, etc.

Condition

Condition (query) parsers.

QueryEvaluator

Returns array that can be passed to CakePHP Query builder as a condition.

use Riesenia\Utility\Condition\QueryEvaluator;

// available fields and operators are defined during consstruction
$evaluator = new QueryEvaluator([
    'pid' => [
        'field' => 'id',
        'operators' => ['=', 'NOT', 'IN', 'NOTIN']
    ],
    'name' => [
        'field' => 'name',
        'operators' => ['=', 'NOT', 'CONTAINS']
    ],
    'price' => [
        'field' => 'unit_price',
        'operators' => ['>=', '>', '<', '<=']
    ]
]);

// simple conditions
$evaluator->parse('price >= 10'); // ['unit_price >=' => '10']

// use AND / OR operators
$evaluator->parse('pid IN 2, 3 AND price >= 10'); // ['AND' => [['id IN' => ['2', '3']], ['unit_price >=' => '10']]]

// use parenthesis for complex conditions
$evaluator->parse('pid IN 2, 3 AND ((price >= 10 OR name = x) OR name CONTAINS y)'); // ... see tests

// throws custom exception for incorrect query
use Riesenia\Utility\Condition\QueryEvaluatorException;

try {
    $evaluator->parse('(pid = 56');
} catch(QueryEvaluatorException $e) {
    if ($e->getCode() == QueryEvaluatorException::MISSING_CLOSING_PARENTHESIS) { // true
        echo $e->getAttributes()['position']; // 0
    }
}

QueryEvaluatorCallable

Returns function that evaluates all attributes of passed array / ArrayAccess returning boolean result.

use Riesenia\Utility\Condition\QueryEvaluatorCallable;

// using configuration from previous example
$evaluator = new QueryEvaluatorCallable([...]);

$condition = $evaluator->parse('pid IN 2, 3 AND price >= 10');

$condition(['id' => 2, 'unit_price' => 7]); // true
$condition(['id' => 4, 'unit_price' => 7]); // false
$condition(['unit_price' => 4]); // false

QueryEvaluatorCart

Returns function that evaluates aggregates condition for riesenia/cart package.

QueryEvaluatorTwofold

Allows passing prefixed condition.

use Riesenia\Utility\Condition\QueryEvaluatorTwofold;

// using configuration from previous example
$evaluator = new QueryEvaluatorTwofold([
    'P1' => [
        'pid' => [
            'field' => 'id',
            'operators' => ['=', 'NOT', 'IN', 'NOTIN']
        ],
        'name' => [
            'field' => 'name',
            'operators' => ['=', 'NOT', 'CONTAINS']
        ],
        'price' => [
            'field' => 'unit_price',
            'operators' => ['>=', '>', '<', '<=']
        ]
    ],
    'P2' => [
        'pid' => [
            'field' => 'id',
            'operators' => ['=', 'NOT', 'IN', 'NOTIN']
        ],
        'name' => [
            'field' => 'name',
            'operators' => ['=', 'NOT', 'CONTAINS']
        ],
        'price' => [
            'field' => 'unit_price',
            'operators' => ['>=', '>', '<', '<=']
        ]
    ]
]);

// example
$evaluator->parse('P1.pid IN 2, 3 AND P1.price >= P2.price'); // ['AND' => [['P1.id IN' => ['2', '3']], ['P1.unit_price >= P2.unit_price']]]
